An Osaka Metropolitan University-led research team investigated the decay time of coherent longitudinal optical (LO) phonons both in a GaAs 1−x N x epilayer and in a GaAs single crystal, to clarify ...

Detecting concealed explosives and chemical threats constitutes a critical challenge in global security, yet current technologies often face significant operational limitations. While X-ray scanners ...

A simple tweak to the usual setup is all that is needed to enhance a spectroscopy technique that uses terahertz wavelengths to probe samples, physicists at RIKEN University, Waka̅, Japan, have ...

Certain materials have desirable properties that are hidden and scientists can use light to uncover these properties. Researchers have used an advanced optical technique, based on terahertz ...

Periodic signal analysis enhances optics and photonics experiments using lock-in amplifiers and boxcar techniques.

Ultrafast laser spectroscopy allows the ascertainment of dynamics over extremely short time scales, making it a very useful tool in many scientific and industrial applications. A major disadvantage is ...

Zomega is a Terahertz-based technology solutions provider. We produce both pre-designed and custom systems for Time Domain Spectroscopy (TDS) and CW applications in both point measurement and imaging ...
